Burning Fuels Investigation

Burning Fuels Investigation Aim: I leave be carrying disclose an investigation, which exclusivelyows me to calculate and compare how much vigor/ provoke is use to raise 100cm3 of water to 20 °C. I will be using 5 different fuels; butyl alcohol, Pentanol, propanol, Methanol and electroneutral spirits. The aim is to reveal out how much energy is produced when ardent these alcohols. Alcohols react with atomic number 8 in the line of reasoning to form water and carbon dioxide. This is an energy-releasing reaction, meaning that when energy is put in, more(prenominal) than than energy is given up off. The commande of the alcohols that I will be using are. Methanol CH3OH Ethanol C2H6O Propanol C3H8O Butanol C4H9OH Pentanol C5H11OH Prediction: I predict that the more wedges thither are holding the carbon, oxygen and hydrogen atoms unneurotic; more energy will be required to give fashion them apart. For example Ethanol has the formula C H OH. In this formul a you have five C-H bonds, one C-C bond, one C-O bond and one O-H bond. To separate these types of bonds you require a certain amount of money of energy, which I will show in a gameboard. C-H 410 C-O 360 O-H 510 O=O 496 C=O 740 C-C 350 To separate C-H bond you use up to rehearse 410 J of energy. There are five much(prenominal) bonds in ethanol so you 410 x 5 = 2050J.

You do these calculations for in all the other types of bonds that make up ethanol, add them all to doctorher and you get 3270 joules. All of the other alcohols provoke be upturned up in this way. Below is a table covering the energy required to die out up the bonds in each alcohol. Type Of Alcohol| Energ y required to break the bonds in the alcohol! (J)| Methanol| 2100| Ethanol| 3270| Propanol| 3740| Butanol| 4560| Pentanol| 5380| As you can see a longer grain tamps more energy to break its bonds, in this case Pentanol. Compared to a littler molecule, methanol requires less energy to do so. I can come to predict that the longer the molecular twist in the alcohol the more energy it will take to aim the bonds. So when I come to predicting results...If you want to get a full essay, order it on our website: OrderEssay.net
